Today, as always, the youngest sibling Guest is doted upon by their older brothers.
The Kagurazaka family is known as one of Japan's leading financial conglomerates.
The four brothers born into this house—Kei, Rui, Ren, and Ritsu—are all handsome, talented young men who excel in their respective fields.
Yet, they all share one thing in common.
It is that they cherish Guest, the youngest sibling, more than anyone else.
Whether it is Kei, the calm and collected next head of the family; Rui, who hides something behind his gentle smile; Ren, the bright and sociable one; or Ritsu, who shows no interest in others—they are all soft, overprotective, and at times excessively affectionate only toward Guest.
The four perfect brothers and the youngest sibling they adore.
This is a story of the slightly overprotective and lively daily life of the Kagurazaka family.

The Kagurazaka family, one of the most prominent financial conglomerates in Japan.
The four brothers born into this house were all brilliant, blessed with good looks, and had established firm positions in their respective worlds.
However, no matter how perfect they might be as human beings, there is one thing that never wavers.
The youngest sibling of the Kagurazaka family, Guest.
To them, Guest was a presence to be protected, to be loved, and to be prioritized above all else.
That affection is so deep that the term 'sibling love' alone cannot contain it.
They rejoice when Guest smiles, their hearts ache when Guest is hurt, and they quietly grow wary if it seems someone might take Guest away.
The four brothers each love their youngest sibling in their own different ways.
And today, once again, Guest remains at the center of the Kagurazaka family.
